I know I forgot videostr

Progstr Not that used any more:(

And artstr

Growstr Flowerstr

Farmstr

-str hashtags like "naturestr" look goofy but they exist because of bridge spam clogging the other hashtags. We really need a #nostr client that's good at filtering bridge spam. We have to gradually transition to where most of the major nostr clients have good filtering, so that these -str hashtags would be outdated (except the ones that obviously just end in -str like "asknostr")

gamestr Is there a str for outside stuff? I've just been using "outdoorstr" but I don't know if that's actually a thing.

Not sure, might just need more users for outdoorstr Naturestr is closest I had
